Study of stress field induced by natural fracture and its influence on hydraulic fracture propagation

Journal of Petroleum Exploration and Production Technology
The change of fracture propagation direction caused by stress interference between fractures is one of the main reasons that affect shale gas productivity.

Investigation Into the Electrochemical Performance of Micron‐ and Nanosized Tin in Diglyme and Carbonate Electrolytes in Sodium Ion Batteries

Advanced Energy Materials, EarlyView.
This study compares Sn particles of different sizes in NIBs using carbonate‐ and diglyme‐based electrolytes. Diglyme electrolytes enable stable cycling despite large volume changes, while carbonate electrolytes degrade rapidly, especially with nanoparticles.

Simulation of Hydraulically Fractured Wells

IOR 1997 - 9th European Symposium on Improved Oil Recovery, 1997
Fractured wells are frequently encountered in petroleum engineering. They can be hydraulically fractured wells to improve oil production or wells intersecting natural fractures. Due to the presence of the fractures, the flow behaviour and the pressure distribution in the vicinity of the fractured well are complex and the numerical modelling for this ...

Sputtering Mechanism of an Unsintered Organic–Inorganic Sputtering Target for Perovskite Solar Cells

Advanced Energy Materials, EarlyView.
An unsintered MAPbI3 sputtering target fabricated via a mechanochemical route enables large‐area vacuum deposition of perovskite absorber layers, while revealing an ion–photon coupled decomposition mechanism that governs target erosion and film composition under RF plasma exposure.

Experimental study on damage law of coal seam under hydraulic fracturing and blast load

International Journal of Coal Science & Technology
Compared with blast mining only, blast mining after on-site hydraulic fracturing can make the mining easier and obtain better mining outcomes. To explore the effects of hydraulic fracturing on the blasting damages in coal seam, blasting experiments were ...

Numerical Investigation of Influence of In-Situ Stress Ratio, Injection Rate and Fluid Viscosity on Hydraulic Fracture Propagation Using a Distinct Element Approach

Energies, 2016
Numerical simulation is very useful for understanding the hydraulic fracturing mechanism. In this paper, we simulate the hydraulic fracturing using the distinct element approach, to investigate the effect of some critical parameters on hydraulic ...

Determining the Protective Effects of Long‐Term Physical Activity, Exercise, Mental Health, and Employment on Sarcopenia—A Result of a Feasibility Study of a Registry

AGING MEDICINE, EarlyView.
This study highlights that physical activity, employment, and mental health significantly influence sarcopenia risk in healthy adults. Working part‐time or full‐time and exercising, especially sports like swimming, alongside good psychological health, may be associated with reduced odds of sarcopenia.

Experimental and modeling study of fluid pressure-driven fractures in Darley Dale sandstone

, 2004
We report measurements of acoustic emissions (AE) generated during formation and growth of pressure driven fractures in cylindrical samples of Darley Dale sandstone that were co-axially pre-drilled in order to allow an internal pressure to be applied.
